Job Contributions
Enterprise Network Operations & Service Ownership
Own the availability, performance, capacity, reliability, security, scalability, cost-effectiveness, and supportability of the enterprise network across data centers, Internet services, cloud connectivity, WAN/SD-WAN, campus LAN, wireless, and supporting network-management platforms. Lead day-to-day operations, engineering, lifecycle planning, and continuous improvement while using service metrics and trend data to identify risk, improve reliability, and ensure engineering work is deliberate, documented, and measurable.
Leadership, Staff Development & Accountability
Lead, coach, and develop engineering staff; establish clear accountability and measurable ownership; delegate effectively; build succession depth; and support certification and technical growth. Create a culture of preparation, engineering discipline, documentation, follow-through, and early identification of operational and technical risks.
Operational Excellence & Performance Management
Establish operating standards for monitoring, incident response, problem management, change control, service requests, maintenance, configuration management, documentation, and vendor escalation. Maintain and review operational metrics related to availability, incidents, problems, changes, network performance, lifecycle risk, monitoring, documentation, workload, vendors, and project delivery, and use trend data to drive root cause analysis and corrective action.
Major Incident Leadership
Serve as senior operational leader for critical network incidents, ensuring rapid triage, clear ownership, effective escalation, disciplined communication, service restoration, and post-incident review. Drive root-cause analysis and documented corrective actions while distinguishing immediate restoration needs from longer-term architectural or operational corrections.
Project & Program Management
Manage network projects and programs using defined scope, milestones, task ownership, dependencies, schedules, budgets, risks, and acceptance criteria. Establish realistic delivery plans, hold project owners accountable, identify schedule or budget variance early, provide concise leadership reporting, and ensure projects are completed with required documentation and operational handoff.
Data Center & Core Networking
Provide leadership for Cisco data center networking, including ACI/Nexus environments, core routing and switching, segmentation, redundancy, high availability, inter-data-center connectivity, and integration with compute, storage, firewall, and virtualization platforms. Review designs and implementation plans to identify risk and ensure resiliency, capacity, and supportability.
Engineering Governance
Require peer review, implementation planning, rollback planning, validation, and documentation for material network changes. Review architectures and implementation plans, challenge incomplete analysis and undocumented assumptions, and ensure high-risk changes are appropriately tested, validated, supportable, and documented.
Documentation, Standards & Configuration Management
Ensure current network diagrams, standards, runbooks, IP/VLAN documentation, configuration standards, support procedures, escalation paths, inventory records, CMDB information, and recovery procedures are maintained and auditable. Require documentation to be updated following major changes and address identified documentation or configuration-management gaps.
Internet & Cloud Connectivity
Maintain highly reliable Internet connectivity and cloud network access. Oversee BGP/ECMP design, DDoS readiness, edge resiliency, routing policy, public/private addressing, NAT where applicable, carrier diversity, and cloud connectivity to platforms such as Azure and AWS.
WAN / SD-WAN Services
Lead WAN and SD-WAN services, including branch connectivity, routing, path diversity, failover, carrier coordination, broadband/Internet backup services, and performance management across critical sites. Monitor route and tunnel stability, latency, packet loss, utilization, capacity, and failover performance and ensure corrective action is taken when needed.
LAN & Wireless Services
Ensure stable, secure, and supportable campus switching and enterprise wireless services, including access/distribution architectures, WLAN controllers, access points, segmentation, QoS, authentication dependencies, and capacity planning. Monitor wireless health, utilization, capacity, and service performance and address recurring operational concerns.
